While I've not ever tried it in this context, do NetShareAdd(), CreateProcessAsUser(), or NetUseAdd() help?

how can i display an integer using MessageBox command?how can i convert an integer value to string?
|
|
|
|
|
char buf[81];
int i = 2;
sprintf(buf, "%d", i);
AfxMessageBox(buf);
|
|
|
|
|
CString buf;
buf.Format ("%i", iMyInt);
MessageBox (buf);
Tada!
Now, if you mean converting 1234 to one thousand, two hundred and thirty four,
as I *think* you asked earlier, I still don't know of a nice neat function.
It would be language dependent too...

Can anyone tell me the url of websites where the efficieny of vc++ developer is tested? ie Online free exam for mfc programming or c++ programming.
Using the tests, the efficiency of the developer is tested.
I have also another question , the question is
What is the importance of ATL in vc++ programming ?
Can any one please help me in this matter.

Efficiency is a very subjective metric. You could ask ten people what makes an efficient programmer and get ten different answers.

Remember that you get what you pay for. While they are not free, you might try brainbench.com[^] and transcender.com[^].

As long as you own at least one fully licensed copy VS then you can ship the crystal reports with commercial software.

Hello,
I need to create a form with multiple buttons instances. In C#, this
would look like this
static string[] strCaption={"Button A","Button B","Button C"};
Button[] btnShow=new Button[strCaption.Length];
for(int i=0 ; i < strCaption.Length ; i++)
{
btnShow[i]=new Button();
btnShow[i].Text=strCaption[i];
btnShow[i].Size=new Size(200,20);
btnShow[i].Location=new Point(10,35*i+20);
btnShow[i].Click+=new EventHandler(Button_Click);
btnShow[i].Tag=i.ToString();
this.Controls.Add(btnShow[i]);
}
I try to code this in C++, but I have a lot troubles setting the
identifiers.
This:
Button* btnShow[]
...
btnShow[i]=new Button();
...
Does not work. Any suggestions/code samples?
Thanks in advance,
Picander

you should allocate first the size of your button array, either statically (Button *btnShow[10];) or dynamically ( Button **ppBtnShow; ppBtnShow = (Button **)calloc(10, sizeof(Button *)); [...] ppBtnShow[i] = new Button;). In the last case don't forget to free your data to avoid memory leaks!

I think it is better to have an array that contains directly the buttons and not the pointers to the buttons (otherwise you will need to destroy your buttons after use, ...).
So it looks like:
CButton* m_pButtonArray;
And to create for example 10 buttons:
m_pButtonArray = new CButton[10];
Then you will need to 'initialize' them using the Create method and then call ShowWindow(SW_SHOW) for all of them.
Hope this helps

Hi Picander,
You forgot to attatch your code, and you didn't mention which compiler your are using VC6.0 or DOT net. Well I gave a try to do the same stuff you have tried, with MCF in VC6.0. You might take a look to it.
//---------------------------------------------------
char *strCaption[3]= {"Button A","Button B","Button C"};
char buffer[20];
int butt_width = 90,
butt_height = 30,
butt_pad = 10;
CButton *myButton = new CButton[3];
// Create a push button.
for(int i=1 ; i <= 3 ; i++)
{
myButton[i-1].Create(strCaption[i-1], WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON, CRect(10, 10 + butt_height * (i-1), 100, butt_height*i), this, 1);
//add code to populate variables
}
//--------------------------------------------------------
Good Day

Thanks for the reply Sohail!
I forgot to mention that I am developing a .NET windows forms application.
Button *myButton = new Button[3];
does not work...
gui\myForm.cpp(87) : error C2691: 'System::Windows::Forms::Button' : invalid type for __gc array element
gui\myForm.cpp(87) : error C3149: 'System::Windows::Forms::Button' : illegal use of managed type 'System::Windows::Forms::Button'; did you forget a '*'?
gui\myForm.cpp(87) : error C2691: 'System::Windows::Forms::Button __gc *' : invalid type for __gc array element
i have tried many other options, as other posted suggested and i still cannot get it working.
I cannot find on the net any similar code sample for c++.

you need to reserve a range of continuous resource ID for your array of buttons; and manually create a ON_CONTROL_RANGE entry in the message map.
The problem with MFC is that you need to have a predefined ID range; you can't create the buttons with no defined ID and have it registered in the message map ( or I think so ).
ON_CONTROL_RANGEBN_CLICKED, id1, id2, OnButtonsClicked)
void YourMethod::OnButtonsClicked(UINT nCmdID)
{
switch ( nCmdID )
{
case id1:
...
case id2:
break;
default:
break;
}
}
One other way would be to create your own class of button that have callbacks that can be sent to the parent window.

Thanks for all the replies! You are great folks!
Here is the combination of your suggestions:
Button* myButtons[];
myButtons= new Button *[20];
for (int i = 0; i < 20; i++)
myButtons[i] = new Button();

hello,
I have a problem. the call SETWINDOWTEXT truncates the length of the displayed text to 259 characters (dialog based, ansi mode) (somebody else reported 159), i don't see any dots, also a lot of space is left on the bar. A getwindowtext will return the full original string.
I try to set a titlebar of my dialog with 3 strings which are left, center and right justified. I do this by inserting a lot of spaces between the strings
Things i can do, but don't wan't to:
- Change the active title bar font.
- Draw my own titlebar.
The following code will work on a 800x600 mode maximized dialog, but not on a 1600x1200.

Hello! I've seen some sample programs on how to use CRectTracker properly, but i only have seen it on ordinary CViews...
I noticed the problem when i used CScrollViews and when I'm scrolling..
When I scroll the view, the CRectTracker also scrolls, thats fine.. But when I scroll all the way to the right, the CRectTracker is supposed to disappear, since its coordinates is out of the view already, and thats fine... But When I scroll back to its position, i expected to see it back, but i didn't.... I want the CRectTracker to be appearing again..
How do i solve this?
